Other Parts Discussed in Thread: TPS40210
i had some issues with the TPS40210EVM. I used the original eval-board (Vin: 8V - 14V / Vout: 24V / Iout: 2A).
I measured the Vout and the ripple of it and it seems to be a problem there. You can see the measurements in the pics below.
The ripple is over 2Vpp. I measured on the Vout (J2) not on the testpoints. According th the datasheet the ripple should be around 500 mVpp.
The ripple creates radiation that shouldn't be there. What can i do to reduce the ripple?
I tried different capacitors on the output, but it didn't work very well.
Is there a easy way to change the FB or the COMP to reduce the ripple?
If i use WEBENCH POWER DESIGNER for the TPS40210, it is a different schematic and not how it is described in the datasheet.
Data WEBENCH (Vin 8-14V / Vout 24V / Iout 2A)
Can someone help me out?
